V snon-snerr Application filed July 5,

To all whom it may concern Be it known that I, HARRY L. YEATON, a citizen of the United States, residing at Boston, in the county of Suffolk and State of 5 Massachusetts, have invented certain Improvements in Shoe-Shaping Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures. 3

This invention relates to the manufacture of shoes, and has particular reference to the shaping ofturn shoes after the lasting, sewhave been performed. These operations leave the upper and the sole of a shoe in a more or less distorted and rough condition, and considerable smoothing and beating out are required inorder to conform the shoe accurately to'the shape of the last and to impart to the upper and the sole a-smooth and finished appearance. A machine for the above purpose is shown in United States Letters Patent No.'1,175,215, granted March 14:, 1916, on anapplication of 0. Ashton, and comprises a rotary beater for leveling the sole of the shoe and an oscillating or pivoted beater for beating the upper adjacent the sole. In the useof that construction, however, it is necessary to hold the shoe bottom upward while beating the upper with the result that the operative can examine the progress of his work only after removing the shoe and'turning it over. Moreover, the shoe engaging face of the pivoted heater is necessarily arranged at a considerably difi'erent elevation from that of the rotary heater, since the former is driven by a cam mounted on the same shaft as the latter. Hence, if the rotary beater is located at the most convenient and efiicient height for the operative, that is about waist high, the pivoted beater will be altogether too high'for tion. r Accordingly, an object of the present-invention is to so arrange the upper beater that the shoecan be conveniently held right side up, that is with its bottom down, while operated upon thereby. With this object in view the upper beating tool is, in the preferred form of the invention exemplified in the drawings, mounted for reciprocation in a horizontal path. 'Since there is no downing, shoe turning and relasting operations comfortable and the most effective opera- N, NEW JERSEY, A CORPORATION on NEW NG MACHINE.

ward component to the movement of this beater, there is no necessity for holding the shoe bottom upward. Accordingly the shoe engaging surface of the beater is made of such a form as to properly shape the upper of a shoe held bottom down, the operative being thus enabled to observe the effect of the tool on the shoe while he is actually carrying out the shaping operation, instead of having to remove the shoe from the beater and turn it over to judge of the progress of .the shaping.

Another object of the invention is to locate the rotary beater, which operates on the sole, and the reciprocating heater for the upper as nearly as possible at the same level. It has been found that with machines of this general type the operative can work most etiiciently with the tool about waist high. With the construction of this invention the difference in elevation ofthe two tools is very substantially reduced, as compared with prior machines, with the result that the operative, while always holding the shoe at the most'convenient and unfatiguing height, can rapidly moveit from one tool to the other as the exigencies of the work require, and this with a minimum of effort and a correspondingly high efficiency.

These and other features of the invention, including certain details of construction and combinationsof parts, will nowbe described vmore fully with reference to the accompany ing drawings, andpointed out inthe claims. 'In the drawings,

Fig. l is a side elevation of the machine;

Fig. 2 isa similar view partly in crosssection and on a larger scale.

As disclosed in the accompanying specification and drawings, the invention is illustrated as embodied in a machine of the general type shown in United States Letters Patent No. 1,076,94c0, granted October 28, 1913,011 an application of O. Ashtonu The machine is provided with. a main frame 4 having a. drive shaft 6 on which are mounted sideby side a rotary beater 8 for beating and leveling the sole of a shoe and a I cam 10. V For lubricating the cam 10 there is provided a pad 12 supported from the main frame at let and pressed against the cam by any suitable means such as a leaf spring 16. Above cam 10 is located a guidewa 20 to receive the stem 22 of a horizonta y reciprocable beating tool provided with a head 24 for operating upon the upper of a shoe. The stem of the beater is provided with a pair of slots 28 supported by rollers 29 suitably mounted in the guideway. Formed integral with the stem 22 of the beater is a depending arm 30 provided with an inclined face 31 for operative engagement with the cam 10. Arm 30 is provided with a slot 32 engaged with a roller 33 mounted in the guideway and co-operating with slots 28 and rollers 29 to provide a roller bearing for the stem in its path of movement. Stem 22 is provided, between its ends, with an upstanding lug 34 which is engaged between the end portions of a pair of spring pressed plungers 38, 39, the compression of the springs being such that the heater is normally held with surface 31 out of the path of movement of cam 10. The spring of plunger 38 also yieldingly limits the forward movement of the beater head 24 and somewhat cushions its blow. An adjustable stop 40 is pivoted to the main frame and may be used, if desired, to limit the effective stroke of the beater. Beneath the head of the beater is placed a stationary support 46 to assist the operative in holding the shoe in position while being shaped.

The beater may be heated in accordance with the usual practice by any suitable means, such, for instance as a gas torch 4A.

In the operation of the machine the shoe may be easily moved by the operative from the upper beating position shown in full lines in Fig. 1 to the sole leveling position shown in dotted lines in the same figure and vice versa as the work progresses. be noticed that as each operation is being performed the shoe is held at substantially the same height, preferably waist high of the operative.

Spring pressed plunger 39 normally holds the beater 24 in inoperative position. When, however, the shoe is pressed by the operative against the beater, the latter is moved rearwardly until its surface 31 comes into the path of movement of the cam 10 which thereupon imparts a rapid series of blows to the beater. Upon the withdrawal of the shoe the beater again comes to rest.

In the drawings the head 24: of the heater is shown as of a form to effectively operate upon the portions of the upper of a shoe ad- 'acent to the toe orthe heel. It is obvious,

owever, that by providing the beater with a head of a different shape it could be adapted to operate upon other portions of the upper of a shoe, such, for example, as the shank.
